Application Jled 'January '17, 1914. 'Seria11\To. 812,733..

To all whom it may conc-em.' j Y Be it known that I, GEORGE v l/YHITE, a citizen of the United States, residing at Hutchinson, in the county of Reno yand btate motor plows.

One of the objects of the invention Yis to provide a motor plow in which the plow is directlycarried by the traction engine thus doinO` awa with an 4extra su) ortin'rr carriage, and in which the raising and lowering of the plow is mechanically effected by power directly derived from the tractiony wheels.

With the foregoing `and other objects in view which will appear as thel description proceeds, the invention resides in 'the 'combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed 'can ybe made within the scope of what is "claimed without departing from the spirit of the invention.

In the drawings accompanying thisspeciicati on and forming a part thereof, thepreferred embodiment of my invention is illustrated, in which Y Figure l is a view in side elevation of my improved motor plow. Fig. `Q yis a top plan view thereof. Fig. 3 is a detail view of the improved portion of the power transmitting and regulating mechanism. Fig. 4 is a vertical section showing in elevation. the means whereby the wiper arm is brought into operative relation with respect to the blades on one of the tractor wheels; Fig. 5 is a section on the line 5-5 of Fig. 2, the view illustrating the pawl and ratchet mechanism whereby the plow lifting shaft is controlled.

Referring to the drawings in which similar reference numerals designate corre-v sponding parts throughout the several y views,'4 is a pair of longitudinal beams which form the longitudinal frame of the machine. The frame 4 as disclosed in Fig. 1 extends upwardly adjacent the front end of the beam to which end is .ipivotally secured the front wheel supporting 1fork '5 which in turn carries the front wheel 6. The

fork 5 is supported in -a suitable 'bearing in the front extremity of the frame 4 and rotatesabouta vertical axis for 'the vsteering ofthe machine. l

A rear axle 7 is mounted in suitable 'bearings 8 carried by the frame 4'and vupon this axle vare mounted two tractor wheels '9. Each tractor wheel includes the central portion 10jwhich is the main drivino-,gear .and to which 'the `spokes `11 'are 4"rigidly secured. The spokes are arranged `in pairs and are disposed at `an angle one to the 'other so Ias to define V-shaped members with the apex v rigidly 'secured to the rim of -the :gear '10. Carried at v'the outer extremities of fthe; spokes `and inclined "at an `angle theretoV are. the paddle blades 12 which are inclined at an langle of approximately v55" to the prolongation o-ffthespoke as clearly illustrated in Fig.. 1. A rim 1-3 extends `through and is secured tothe various paddle blades and strengthens the entire construction `and also preventsa transverse skidding of the wheels. Forming the blades 'at the angle mentioned provides that 'when the Itractor wheel Ysinks the usual amount into the ground the Vblade will as the wheels are'driven forwardly contact with the ground `in 'a flat manner and will thus obtain 'a maximum `pressure thereon and impart 'themaximum tractive effort to the machine. A further feature of advantage arises 'from :the fact that as the wheels lare rotated, the lblades will 'bep with-v' drawn from the ground and b'e moved ina substantially longitudinal manner so that the wheels will 'beywhat might be termed self-cleaning, by which is meant that `the blades will tend to rid themselves ofthe earth or other material'which might cling a spur-gear 2O which in turn drives -thejex-v ternal gear 21 of the differentialy 22. One

end of the shaft 19 is mounted within the eccentric bearing 20 which may be rotated by the lever 2l to thus bring the upper periphery of the friction wheel 1S into contact with the inner surface of the rim 17 or, by shifting the lever 21 the said friction wheel is shifted into a neutral position out of contact with the fly wheel 16 or into a lowered position in which the lower periphery of the friction wheel 18 will contact with and be driven by the hub 22 of the flywheel and in a reverse direction as well as at a much lower speed. 1t is to be noted that the bearing; 23 at the remote end of the shaft 19 is so constructed that the shaft 19 may shift by the eccentric bearing as described.

rlhe differential gearing 22 is mounted upon the shaft 24 upon the extremities of which shaft are mounted the gears 25 which mesh with and drive the main gear 10. The tractorwheels 9 are loosely mounted upon the shaft 7 so that the said wheels may be driven at different speeds by means of the differential gearing 22. A pair of band brakes 26 are disposed upon the opposite sides of the differential gearing and are actuated by the pedals 27. When one of the band brakes is applied one of the tractor wheels will be retarded whereas the opposite tractor wheel will be accelerated to thus turn the machine around in a small space as it is thought will be readily appreciated.

The front wheel supporting fork 5 is provided with the outstanding arm 28 and to which are secured the connecting rods 29 which in turn are connected with the lever 30 which latter is provided with the-foot engaging portion 31 by means of which the front wheel may be turned to thus steer the vehicle cooperating with the pedals 27 to turn the machine in a small arc.

The longitudinal beams 4 extend a distance in the rear of the rear axle 7 as at 3 2 and support the angularly disposed shaft 33 and the angularly disposed beam 34. A plurality of plows 35 35 are pivotally secured at their front extremities to the downwardly extending rigid struts 36 which are carried by the beam 34 except the outermost plow 35 as illustrated in F ig. 1 are connected by means of thc links 37 to` arms -38 which are rigidly secured to the shaft 33.

r1`husl as the shaft 33 is rotated the rear extremities of the plows are either raised or lowered as itis thought will be readily appreciated. 1n order to mechanically rotate the shaft 33 an arm 39 is movably secured thereto and is so arranged that the path of motion of its extremity intersects the path of rotation of one of the tractor wheels 9. The arm 39 is connected with the outermost plow 35 by means of a link which upstands above the arm 39 to form a resilient handle 4U by means of which the wiper arm 39 may be brought manually into the path of rotation of the wheel 9 and when so positioned one of the paddle blades will strike against the wiper arm and raise the same until the wiper arm will pass out of the path of motion the wheel. 1n order to prevent the shaft from dropping back after it has been rotated by the wheel the pawl 42 is provided which coacts with the ratchet 41 to hold the same against reverse rotation. The upper extremity of the pawl is provided with the foot engaging portion 43 whereby it may be released and the plows allowed to lower into engagement with the ground.

A seat 44 is provided upon which the operator 4of the machine rests and when in such position he is able to reach the various controlling mechanisms as described to suc* cessfully operate the engine plow. Because the shaft 33 is disposed at an acute angle to the plane in which the wheel 9 rotates, the arm 39 will automatically clear itself from the blade of the wheel 9 as the latter rotates. rEhe connection between the lever 40 and the beam of the plow 35 is a somewhat loose one, to the end that the part 39 may have the necessary lateral movement.

Having thus fully described my invention, what I claim is 1. A motor plow comprising tractor wheels with outstanding blades, a plow supiporting beam supported by said wheels, a plow elevating shaft extending parallel to said beam, a plow pivotally secured to the beam and linkedly secured to an arm rigidly carried by said shaft, and mechanical means extending in the path of motion of the outstanding blades of the tractor wheels for mechanically rotating the shaft through a limited arc for the raising and lowering of the said plow.

2. A motor plow comprising tractor wheels with outstanding blades, a tractor frame carried thereby, a rearwardly extending beam carried by said frame, a plow secured thereto, a shaft carried by said frame and provided with an outstanding arm, links extending between the said arm and the said plow for the raising and lowering thereof, and a wiper arm carried by said shaft arranged with a portion of its path of rotation intersecting the path of rotation of the tractor blades.

3. A motor plow comprising tractor wheels with outstanding blades, a tractor frame carried thereby, a rearwardly extending beam carried by said frame, a plurality of plows secured thereto, a shaft carried by said frame and provided with a plurality of outstanding arms, links extending between said arms and said plows for the raising and lowering thereof, a wiper arm carried by said shaft arranged with a portion of its path of rotation intersecting the path of rotation of the tractor the arc of oscillation of the wiper arm interblades, and means engaging the said shaft secting, for a predetermined distance, the preventing the reverse rotation thereof. path of rotation of one of the wheels.
